ABSTRACT:
A receiver circuit (200) is provided, comprising: an agile clock (250) configured to generate an agile clock signal having a controllable agile clock phase based on agile clock control signals; a code processor (260) configured to receive an incoming signal and the agile clock signal, and to generate an on-time signal (110) and an error signal (120) corresponding to the incoming signal; a coarse acquisition circuit (270, 310) configured to identify a coarse acquisition phase based on a total power of the on-time signal and plus a total power of the error signal; a fine acquisition circuit (270, 320) configured to identify a fine acquisition phase based on the coarse acquisition phase and a magnitude of the on-time signal; and an acquisition controller (270, 330) configured to control operation of the coarse acquisition circuit and the fine acquisition circuit, and to provide a final acquisition phase as a current phase based on the one or more fine acquisition phases.
